eBay doesn't accept emails or provide a phone number. To contact eBay you need to click on "Help & contact" or "Contact us" at the top or bottom of every page, or use this link: https://www.ebay.co.uk/help/home
It's seldom necessary to speak to eBay. Most questions that users ask can be answered in eBay's online help pages. Have you tried clicking on the Help & Contact ink above and entering a few keywords in the search field?
If you still stuck, why not explain what the problem is? Someone here will probably know the answer, and be able to answer it more quickly than eBay will.
